Is improving mental health possible in digital weight management?

We published a study investigating the effect of our Tier 3 digital weight management service on the depression scores of people living with complex obesity. We know that there appears to be a bi-directional link between depression and obesity (Luppino et al., 2010), and we were interested in understanding further how digital innovation can support people living with obesity from a psychological perspective.


Fifty-four patients living with complex obesity in England and Scotland were evaluated after being referred onto Oviva’s digital Tier 3 Weight Management programme, by their GP or local NHS provider.

Participants were asked to complete the self-reported Patient Health Questionnaire 9 (PHQ-9), a well-validated and widely used measure of depression. The questionnaire was completed at the beginning, and at 3 and 6 months of Oviva’s digital Tier 3 Weight Management programme, to understand specifically, the changes in depression symptoms over time during this programme. PHQ-9 scores of 10 or above are classed as a clinical case for depressive symptoms.


Participants reported a decrease in their average PHQ-9 score as they progressed through Oviva’s digital Tier 3 Weight Management programme, with a huge 48% of participants moving to a less severe depression category after 6 months.


The findings demonstrate the broader, holistic benefit Oviva’s programmes can have for participants. Oviva’s delivery model combines psychological intervention and behaviour change support with app technology. This remote blended-care approach is likely to have played a fundamental role in reducing depression symptoms in people with complex obesity, alongside significant reductions in their BMI and providing them with the tools to make sustainable changes to their diet and lifestyle.

It is encouraging for remote digital interventions, as the ease of access to care and convenience can increase uptake and engagement from traditionally under-represented groups, removing the barriers to access thereby tackling health inequalities. In addition, the positive holistic effects for participants identified here suggest that weight management services should target improvements in depression alongside other outcomes.

Our peer reviewed evaluation shows significant improvements in the depression scores of people living with complex obesity when taking part in our specialist digital programmes.

“This shows how people living with obesity can benefit from the holistic care provided by digital weight management programmes. Digital delivery will help cut the backlog in our NHS and make care more accessible for working people, those living in remote areas, and from ethnic minority communities.”
